Hi Amit,
commit ef11982dd7a657512c362242508bb4021e0d67b6 (Add support for
interrupt EP) actually broke testusb for MUSB when MUSB is the gadget.
The reason is that we're requesting an endpoint with a 64-byte FIFO, but
later deciding to use the same endpoint with wMaxPacketSize set to 1024
and MUSB errors out because the endpoint was selected for 64-byte only.
This only happens when trying to set alternate setting 2 and it's pretty
easy to trigger.
This issue was brought up earlier by Sebastian. He even submitted a
patch for the same and there were discussions over it.

However, things were never concluded. Using module parameters should get
it working but that isn't a clean solution.
What do you suggest?
Regards
Amit Virdi
